Portion Control is a good 'first step' to positively changing your calorie intake, especially if your having trouble with the realities if the time commitment of clean eating. Clean eating requires planning and a time commitment to packing lunches and snacks, and an effort to using ingredients closest to the original source of ingredients.

But, you can reduce your calorie intake regardless by using this handy guide to measuring your food:

1. One cup of raw veggies is equal to your two hands cupped together.

2. A medium piece of fruit is equal to your balled fist.

3. 1/4 cup of nuts is equal to the palm area of your hand.

4. 3 oz. of meat or poultry is roughly the same as the size of a digital camera.

5. 1 slice of whole wheat bread shouldn't be bigger than an i-pod ( read ingredients on these. They can vary up to 100 calories per slice based on the brand).

6. 1/2 cup of whole grain rice or pasta equals 2 golf balls ( imagine how many cups you get at most Italian restaurants!).

7. 3oz. of fish is the same as a man's wallet ( though salmon is dramatically more calories than Mahi Mahi, scallops, or shrimp).

Try to think of these measurements when making your food choices and you may see a reduction in your overall weight.
